CYLINDER FOR WASHING-MACHINES.

Specification of Letters Patent.

Patented Aug. 16, 1910.

Application :filed March 6, 1908. Serial No. 419,458.

To all whom 'it may concern:

Be it known that I, JOHN A. MCKEE, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Cylinders for VVashing-Machines, of which the following is a specification.

My invention relates to a new and useful improvement in cylinders for washing machines, and has for its object to provide an exceedingly simple and effective construction by the use of which a flow of water will be caused to pass through the cylinder in one direction when said cylinder is revolved, and in the opposite direction when the cylinder is revolved in an opposite direction, and a further object of my invention is to so ar range the openings in the cylinder as to cause the waterto flow from the tank or outer casing through the cylinder below the water level.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specication in which- Figure l is an elevation of a cylinder made in accordance with my improvement. Fig. 2, is a longitudinal section. Fig. 3, an end view thereof. Fig. 4:, a cross section at the line of Fig. 1. Fig. 5, a detail of a portion of one of the outer ribs. Fig. 6, an end view of one of the outer ribs. Fig. 7, a detail of a portion of one of the screens. Fig. 8, a detail view of a portion of one of the inner ribs. Fig. 9, an end view of one of the inner ribs, and Fig. 10, an end view of one of the fillers. Fig. l1 a side view of the fillers.

In carrying out my invention as here embodied, A represents the two heads of the cylinder here shown as composed of three sections secured together in any suitable manner, and B are the outer ribs, the ends of which are secured to the heads, and the sides of each of these ribs are inclined inward as clearly shown in Figs. 3 and 4, and C represents the inner ribs, the sides of which are inclined in an opposite direction and at the same angle and are also secured to the heads in such manner as to form two passages D for each inner rib, said passages being at an angle to each other.

The outer ribs have the grooves F formed lengthwise thereof, while the inner ribs have corresponding grooves Gr also formed lengthwise thereof, and when these ribs are in place the grooves lie in the same plane and are adapted to receive the edges of the screens H. These screens I-I may be made in any suitable manner, but are here shown as being strips of perforated metal and when set in the grooves serve to strengthen the cylinder and permit the free flow of water to and from the same, while retaining the articles to be washed within the cylinder.

E are the fillers adapted to fill the space between the outer and inner ribs where they rest upon the heads so as to make a circular bearing surface for the metal bands I, which latter are secured by screws or otherwise over the ribs and fillers, holding them in place. Where a single compartment cylinder is used there would only be two heads, but as it is customary to use a two compartment cylinder a third head A serving asa partition is secured midway between the end heads, in which case a third band I is secured around the ribs.

M represents the doors, which are secured to the cylinder by the strap hinges N, and these doors may be locked in their closed position by the bolts O.

P and P represent tumbling ribs secured to the heads and extending lengthwise inside of the cylinder for striking and tumbling the articles that are to be washed when the cylinder is revolved.

In the use of power washing machines having outer tanks and inner cylinders, it is customary to revolve the cylinder first in one direction a certain number of revolutions and then in the opposite direction, and when 100 my improved cylinder is used and this method is followed, the water in the outer tank will be caused to flow through one set of the passages D when the cylinder is revolved in one direction and in the opposite set of passages when the cylinder is revolved in the opposite direction, and the angles of these passages are such as to create currents of considerable force below the water level u l v a and this 1s of considerable lmportance.

Having thus fnlly described my invention, the extreme outer surfacesof saidV minor ribs 10 what I claim as new and useful, is-

A cylinder for washing machines com- Y prislng drum-heads, a main set of ribs havl ing internal surfaces of pyramidal form, interitting minor rib members having their outer surfaces of pyramidal form, and screens supporting said minor rib members in unsagging relation to said main set of ribs,

being within the surfaces of said major ribs.

In testimony whereof, I have hereunto afiXed my signature in the presence of two subscribing witnesses.
